Question

To protect galvanometer from possible damages due to large current, which of the following should be connected to its coil:

• A. Low resistance wire in series
• B. High resistance wire in series
• C. High resistance wire in parallel
• D. Low resistance wire in parallel

Hint:

Always use a high resistance wire in series when protecting delicate instruments like galvanometers from high current.

Answer 1

The Correct Option is B

To protect the galvanometer from large currents, a high resistance wire is connected in series to limit the amount of current passing through the galvanometer. This ensures that the current is not large enough to cause damage.
